The main difference between a general cleaning and a deep clean is that a general cleaning focuses on regular maintenance, while a deep clean hones in on the nitty gritty details of cleaning that may not impact your day-to-day life. For example, it’s important to wipe down your counter and have a clean place to cook regularly, but you may not think twice about pulling out your stove to clean behind it until it’s time for a deep cleaning.

A small amount of diluted bleach is okay to pour down a garbage disposal. As part of your weekly garbage disposal maintenance, use 1 teaspoon of bleach with your concoction of ice cubes and lemon peels. Turn on the disposal and run the water until the blades chop up the ice cubes.

Any more bleach in your disposal can harden oils and greases in your drain, which can cause problems. Always wear gloves when working with bleach, and know that you really don’t need bleach at all—vinegar, baking soda, salt, and ice should do the trick.

As a general rule, you should clean your oven at least every three months, though this depends on how often you use it and the amount of residue buildup. A clear sign that your oven needs cleaning is if you notice smoke or a burning smell during use. Many ovens have a self-cleaning cycle, which heats the oven to an extreme temperature. If you use this feature, stay home while it runs and consider ventilating the room, as it can create smoke. For manual cleaning, you can make a paste of baking soda and water or use white vinegar before resorting to harsher, store-bought oven cleaners.

Before hiring a cleaning service for your home, it's wise to ask several questions. Find out what services they offer, whether they work alone or with a company, and if they can provide references. It's also important to ask if they conduct background checks on employees. Inquire about their scheduling, availability, and when they can provide an estimate. Confirm if they have insurance, offer a guarantee, and bring their own cleaning supplies and equipment. You should also clarify if you need to be home during the cleaning, what arrangements are necessary for pets, and if there is a written contract. Finally, ask how they set their rates and if they are available for emergencies and what those charges would be.
